Abstract
The invention provides an oxygen-enriched bottom-blowing double-port sulfonium-discharging inclined smelting furnace, relating to the field of colored metallurgy. The smelting furnace comprises a furnace body, a feed inlet, a low-position sulfonium-discharging port, a sulfonium-discharging port, a slag outlet, a smoke channel, oxygen guns, oxygen-enriched air, copper sulfonium, slag liquid and mineral aggregates. The smelting furnace is characterized in that the furnace body is longitudinally inclined by a small angle, the oxygen guns are in staggered and crossed arrangement in two rows, the distances among the oxygen guns are gradually reduced from the start end to the final end, and the low-position sulfonium-discharging port, the sulfonium-discharging port and the slag outlet are all arranged on the end surface of the final end of the furnace body. Compared with the prior art, the smelting furnace has the advantages of reasonable design, simple structure, uniform mixing of the oxygen-enriched air and the copper sulfonium, rapid and violent reaction, high free degree of various ions, long settling and separating time, large space, low energy consumption, wide application range of the mineral aggregates, high multi-metal capturing rate, smelting cost reduction, smelting efficiency improvement, and the like, thereby having good generalization and using values.
Description
One, technical field:
The present invention relates to the nonferrous metallurgy field, a kind of specifically oxygen-enriched bottom-blowing double-port sulfonium-discharging inclined smelting furnace.
Two, background technology:
Non-ferrous metal smelting furnace under the prior art; Around the theme of consumption reduction, reduction of discharging, synergy, new technology, new technology emerge in an endless stream, the selectivity at aspects such as mineral aggregate grade, the association of many metals, particle order number, water content; Aspect such as adaptability and utilization rate; At the aspects such as energy resource consumption of solid, liquid, gas fuel and electricity, effluxing and aspect such as utilization again of waste gas, waste liquid, waste residue, at aspects such as metal target, the polymetallic capture rates of association; And aspects such as the disposal efficiency of above aspects and cost reduction, all innovation with rapid changepl. never-ending changes and improvements and progress are taking place.But all still there are potentiality and deficiency in above each field, remain further to be excavated, innovate and overcome.
Three, summary of the invention:
The objective of the invention is to above potentiality and deficiency; Theme around consumption reduction, reduction of discharging, synergy; Provide a kind of reasonable in design, simple in structure, energy consumption is low, be suitable for the wide model of mineral aggregate, many metals capture rate is high, reduce smelting cost, improves the oxygen-enriched bottom-blowing double-port sulfonium-discharging inclined smelting furnace of smelting efficient.
The technical scheme that the present invention reaches above purpose is:
A kind of oxygen-enriched bottom-blowing double-port sulfonium-discharging inclined smelting furnace comprises that body of heater, charging aperture, low level are put the sulfonium mouth, put the sulfonium mouth, slag notch, flue dust road, oxygen rifle, oxygen-enriched air, copper matte regulus, slag liquid and mineral aggregate, it is characterized in that the vertical small angle inclination of body of heater installs; Many oxygen rifles in smelting furnace top, bottom one side; Double dislocation intersects lays, and oxygen rifle spacing is dwindled to the terminal from top gradually, double oxygen rifle at an angle in opposite directions diagonal cross spray oxygen-enriched air; Charging aperture evenly is arranged in the body of heater top of oxygen rifle correspondence position; Low level is put lower edge, the center side that the sulfonium mouth is arranged at body of heater terminal end face, puts sulfonium mouth lower edge and puts sulfonium mouth upper edge a little more than low level, shifts to install laterally.
Oxygen-enriched bottom-blowing double-port sulfonium-discharging inclined smelting furnace of the present invention is compared with prior art, has following significantly excellent accounting for:
1, double oxygen rifle intersects angular injection at an angle in opposite directions, makes the oxygen-enriched air jet bigger at the copper matte regulus medium range, and it is longer to stop interval; Mix more fully more even with copper matte regulus; Contact area is bigger, and reaction is rapider, violent, thorough, and rare free oxygen gets into the slag liquid layer; Avoid or reduce tri-iron tetroxide generating, avoid foamed slag harm.
2, oxygen rifle spacing is dwindled to the terminal from top gradually, and copper matte regulus is reacted when shifting out oxygen rifle district thoroughly, and temperature reaches peak value, and various particle freedoms are the highest, are easier to the sedimentation in the decanting zone, with the class layering.
3, the vertical small angle inclination setting of body of heater; Not only strengthened the terminal copper matte regulus degree of depth; Caused vertical straight slope of bottom of furnace body simultaneously; Make original horizontal curve slope become double inclined plane in length and breadth, make in the copper matte regulus different specific weight particle precipitation more rapidly, more concentrated, different overflows that make low level put the sulfonium mouth, to put sulfonium mouth and slag-drip opening are purer.
4, low level is put the sulfonium mouth, is put the sulfonium mouth, slag-drip opening exists together the smelting furnace terminal; Prolonged reaction zone to the distance between outlet; Make the copper blunderbuss in smelting furnace, utilize sedimentation and separation time and space to greatest extent, reach best sedimentation separation effect, the comprehensive capture rate of many metals is higher.
5, low level is put the position of sulfonium mouth, assembles the space for a small amount of high specific gravity noble metal has left independently sedimentation, and capture rate and content are higher.
Thereby the present invention has good value for applications.
